Returns:

def blank?
  false
end

Enables the use of byte calculations and declarations, like 45.bytes + 2.6.megabytes

def bytes
  self
end

def days
  ActiveSupport::Duration.new(self * 24.hours, [[:days, self]])
end

3.dup # => TypeError: can't dup Fixnum
3.duplicable? # => false

Numbers are not duplicable:

def duplicable?
  false
end

def exabytes
  self * EXABYTE
end

def fortnights
  ActiveSupport::Duration.new(self * 2.weeks, [[:days, self * 14]])
end

def gigabytes
  self * GIGABYTE
end

def hours
  ActiveSupport::Duration.new(self * 3600, [[:seconds, self * 3600]])
end

def html_safe?
  true
end

so we can feed them to JavaScript functions like getTime().
Used with the standard time durations, like 1.hour.in_milliseconds --

def in_milliseconds
  self * 1000
end

def kilobytes
  self * KILOBYTE
end

def megabytes
  self * MEGABYTE
end

def minutes
  ActiveSupport::Duration.new(self * 60, [[:seconds, self * 60]])
end

def petabytes
  self * PETABYTE
end

(4.months + 5.years).from_now
# equivalent to Time.current.advance(months: 4, years: 5)

2.years.from_now
# equivalent to Time.current.advance(years: 2)

1.month.from_now
# equivalent to Time.current.advance(months: 1)

as well as adding or subtracting their results from a Time object. For example:
These methods use Time#advance for precise date calculations when using from_now, ago, etc.

Enables the use of time calculations and declarations, like 45.minutes + 2.hours + 4.years.
